PPP and HDLC are both methods for accessing the services of WAN providers by using protocols that connect peer devices.
A communications system known as a wide area network covers a huge geographic area. Leased telecom lines are frequently used to set up wide area networks (WAN).
One of the most popular kinds of WAN connections is a point-to-point connection. PPP connections are used to link LAN segments within a company's network as well as LANs to service provider WANs. The High-Level Data Link Control protocol is known as HDLC. HDLC is a Layer 2 protocol, same like the other two WAN protocols discussed in this article (see OSI Model for more information on Layers). A straightforward protocol called HDLC is used to link point-to-point serial devices.
PPP is a byte-oriented protocol for communication over point-to-point links, whereas HDLC is a bit-oriented protocol for communication across point-to-point and multipoint links. HDLC is a bit-reliant, code-transparent synchronous data link layer protocol.

Making policy has traditionally been seen as Whitehall’s main function. Yet, despite over a
decade of sustained efforts to improve policy making, civil servants, politicians and academics
continue to express concerns about the way policy is made, and whether it is ready to meet
future challenges. These concerns need to be taken seriously. The strength of policy making is
integral to the strength of government as a whole, and that of the country at large. When
policies fail, the costs (whether monetary or otherwise) can be significant.
There would be a compelling case for studying policy making even if Whitehall could look
forward to a period of stability. Clearly, this is not the case. Departmental administration
budgets are being cut by an average of 33% over four years, and the Prime Minister has
promised “a total change in the way our country is run”.

The Institute’s approach
In the face of these challenges, policy
making will need to change – both in its function and its organisation. The Institute’s Better
Policy Making theme aims to show how this can be done.
Answer:
pitch
Explanation:
The answer is "pitch".
A pitch of the sound corresponds to the frequency of the sound, meaning whether the sound wave is of higher frequency or of lower frequency.
Sounds are made of vibrating particles called sound waves. If the sound waves vibrate fast they are said to have higher pitch or if the sound waves vibrate slow, the sound waves are said to have lower pitch.
Thus Enrico is having trouble identifying the sound waves between a tuba and a piccola based on the pitch of these sounds.
Thus the answer is
"pitch".
Answer: In year 1871, i.e. era of classic anthropological, Edward Tylor defined culture as “a convoluted whole which tends to majorly includes factors such as belief, knowledge, law, art, morals, custom, and several other habits and capabilities acquired by human when they tend to act as a member of their respective society”.
